Thread: Tranny???

Moved your thread over to the tranny section.

If the transmission is shifting into all gears ok then dont worry about solenoids or internal trans problems yet. The pcm-powertrain control module- controls all transmission functions, so if you have any engine sensors intermittantly acting up or failing then it will have a direct effect on transmission operation. I would have the car checked for any trouble codes in the history as well as use a scan tool to view some general engine data such as the TPS, MAF, MAP, 02 sensors, VSS, etc to assure that everything engine wise is running as it should. It will shift into 4th around the 40-46mph mark at light throttle and also the torque converter has a clutch inside that will lock up and make the car feel a bit lazy, but it shouldnt be to the point you are describing nor shift the shift timing be hit and miss. Have the car checked out for the above areas of the engine and trans data and see if anything turns up.
